TR175R – GOULD 175A 600V CLASS RK5 TIME DELAY FUSE

The TR175R is a Class RK5, 175A 600V time delay fuse with a 200kA interrupting rating, manufactured by Gould (now part of the Mersen/Ferraz Shawmut family). Class RK5 fuses fit any Class RK, H, or K fuseholder rated for 600V and 200A or greater — including standard 3-pole and single-pole industrial fusible disconnects and safety switches designed for fuses up to 200A 600V.

• Fuseholders: Compatible with Class RK5/RK1-rated holders; the RK5 rejection feature prevents installation in Class H holders, ensuring proper protection levels.
• Cross-references: The TR175R may be replaced by equivalent Class RK5 time delay fuses from Mersen (formerly Gould/Shawmut), Eaton Bussmann, or Littelfuse — confirm the amperage, voltage, class, and time-delay rating match exactly.
• Typical applications: Motor branch circuits, industrial machinery, and feeder protection where time delay is required to ride through motor inrush currents.
